Here is the problem. It seems as if all four of my crossmember bolts are too long. They all screw in about 85% of the way and then feel as if they're bucking on the frame. As a result of this, the crossmember itself isn’t sitting flush with the chassis in the front or rear. When I back in & off the gas I hear a lot of clunking around, because the crossmember is screwed up all the way. What do I do? The only thing I can think of is getting shorter bolts.
